Heart shaped embroidery hoop

At the request of one of the MakerWorld users, I made this heart-shaped embroidery hoop. It’s not perfect, but this is what I’ve managed to achieve (so far). There may be some stringing on the inside where the two parts meet, but you can simply remove this after printing. This is the version in which I can clamp a piece of fabric the tightest without it slipping. Because of the shape, that’s quite a challenge. 

You need to add a m4 screw(like the one in the photo) and hex nut.

I hope you like it.
